To all whom it may concern:

Be it known that I, ALoNzo E. RHoADns, a citizen of the United States,and resident of Hopedale, county of Worcester, State of Massachusetts,have invented an Improvement in Yarn-Spinning Apparatus, of which thefollowing description, in connection with the accompanying drawing, is aspecification, like characters on the drawing representing like parts.

This invention relates to that type of apparatus wherein means areprovided to effect the winding of yarn upon a yarn-receiver or bobbin insuch manner that a preliminary winding or bunch is first laid andthereafter 7 a main or service winding of yarn is laid, such woundbobbins being thereafter used in the shuttles of automaticfillirig-replenishing looms of the feeler class. In such looms thechange of filling is effected by or through the feeler when the yarn hasbeen woven off down to a predetermined extent, the preliminary windingor bunch containing suflieient yarn to maintain continuity of thefilling when a change of filling is effected through the action of thefeeler.

As will be manifest to those skilled in the art any interference withthe free drawing off of the yarn in the shuttle during the Weavingoperation invariably tends to yarn breakage, and in practice I haveobserved that there is at times a tendency to yarn breakage caused bythe yarn in the main winding catching over the end of the bunch nearerthe head of the bobbin. This catching is due to an abruptness orsquareness, as it may be termed, of the inner end of the preliminarywinding, so that the final layers of the main winding behind such abruptend of the bunch are caught or held thereby and broken by the forwardpull of the yarn in the direct-ion of the tip of the bobbin. As theresult of study and observation I believe that this abruptness of theinner end of the bunch is a result of the manner in which the same hasbeen formed heretofore, and is due to the fact that the gain dependentupon the winding mechanism of the builderanotion is insufficient for thelaying on of the yarn which forms the preliminary winding. It will beunderstood that the gain of the traverse is that movement of thering-rail whereby at each up-stroke it rises a little higher, and ateach downstroke descends not quite so low as on the previous downstroke,to lay the yarn in successive layers upon the bobbin. When thebuilderarm has a constant stroke the traverse will be of constant lengthunless modified, and in bunch-building apparatus such modification hasbeen effected heretofore in such manner that during the preliminarywinding or formation of the bunch the traverse is shortened, and thenautomatically lengthened to its full extent when main winding is begun.The gain when winding with full traverse gives satisfactory results inpractice, but the same gain when winding with the short traverse appearsto be insufiicient to impart the desired gradual taper to the bunch,particularly at its inner end, as successive layers of yarn are laid,giving the abrupt or more nearly cylindrical shape to the bunch insteadof the desired taperended contour.

My present invention has for its principal object the production ofmeans, in an apparatus of the type hereinbefore mentioned, whereby thenormal gain is increased during the formation of the preliminary windingof yarn upon a yarn-receiver, at the time of the shorter traverse,whereby such winding has a tapering end over which the yarn will notcatch during the weaving off when the bobbin is in the loom-shuttle. Ihave also simplified the construction of the apparatus in dilferentparticulars, and provided simple and readily adjusted means fordetermining the amount of yarn to be laid in the prelii'ninary winding.

The various novel features of my invention as embodied in one practicalform will be fully described in the subjoined specification andparticularly pointed out in the following claims.

Figure 1 is a front elevation of a portion of a spii'ming-frame showingthe buildermotion and the controlling connections between it and thering-rail, embodying one form of my present invention, the apparatusbeing shown in. readiness to begin the formation of the preliminarywinding or bunch, the ring-rail being at the bottom of its traverse;Fig. 2 is an enlarged detail in front elevation of the traverse shiftingor changing means whereby the shorter traverse with which thepreliminary winding is laid is shifted or changed auton'iatically at theproper time to the longer traverse with which the main or servicewinding is laid;

Fig. 3 is a top plan view of the parts illustrated in Fig. 2; Fig. 4 isa longitudinal section through the carriage on the line 44, Fig. 3,showing the traverse controlling member and the shiftable or variablefulcrum with which said member cooperates during the preliminarywinding; Fig. 5 is a front elevation of the rotatable member of themeans by which is determined the number of layers of yarn to be laid inthe preliminary winding; Fig. 6 is an enlarged elevation of ayarnreceiver or bobbin showing the completed preliminary winding orbunch thereon, the completed service winding being indicated by dottedlines.

Having reference to Fig. 1 the frame A, spindle-rail R on which aremounted suit-- able rotatable spindles S, the vertically-reciprocatingring-rail R provided with a ring R for each spindle, the lifter-rods L(only one being shown), a cooperating rocker as L for each lifter-rod,one of said rockers having an attached weight 1V to elevate thering-rail, the upturned rocker-arms L rigidly connected with saidrockers, and the connecting links, as L to transmit from the weightedrocker L simultaneous reciprocating movement to the several lifter-rods,may be and are of usual construction and operate in a manner well knownto those familiar with spinning or similar yarntwisting machines.

The builder-motion comprises the builderarm Z) fulcrumed at 6* andprovided with a roller or other stud b to cooperate with an actuating ortraverse-cam B, (which in practice may be of the general shape shown inmy United States Patent No. 798704, dated September 5, 1905), and thewinding mechanism mounted on the arm, including the drum b thepick-shaft 6 having the usual worm to rotate the wormgear 6 attached tothe drum, effecting gradual rotation of the latter, the pickwheel b andthe actuating pawl 1), operating as usual, the builder motion as a wholebeing of wellknown construction, the builder-arm being given a constantstroke by the cam B, and the gradual rotation of the drum letting offthe attached chain or other connection 13*, attached at one end to thedrum and at its other end being connected indirectly with the ringrail,to effect the gain of the traverse. The chain B leads up over aguide-sheave 1 on the girder A and is attached to a bridle made bybending a rod to present long and short portions 2, 3, the latter beingconnected by a chain or other flexible member 4 with a hook 5 on acarriage 6, having lateral projections 7, Fig. 3, to slide in horizontalguide-ways 8 in the sides 9 of an open frame, said sides being rigidlyconnected by crossbars 10, the frame being rigidly attached to thegirder A". Said carriage has a longitudinal slot 11 therein to receivethe lower end of a traverse-shifter, shown as a lever 12 pivoted nearits lower end at 13 on the carriage and having its longer end upturnedabove the carriage and provided with a hole 14 to receive the hook 15formed on the long part 2 of the bridle hereinbefore referred to. Thesaid part 2 is a species of link directly connecting the chain B and thetraverse shifter, while the bridle part 3 and flexible member 4 providea separate connection between the carriage and the chain B which may betermed the builder connector, and the respective connections between itand the traverseshifter 12 and carriage 6 may be termed the auxiliary ortraverse-shifter connector and the main or carriage connector,respectively.

As most clearly shown in Fig. 4 the shifter 12 has a series of threeholes 16 between the hole 14 and the pivot 13, and nearer the latter,any one of said holes be ing adapted to receive the hook 17 of aflexible member or chain 18 attached to the next rocker-arm L beyond thecarriage, partly shown in Fig. l.

The preliminary winding or bunch is governed as to its traverse by orthrough oscillation of the lever 12, transmitted to the ring-railthrough the chain 18, rocker-arm L etc., and the shortest traverse forthe preliminary winding is effected by catching the hook 17 in the hole16 nearest the shifter pivot 13, while the longest traverse for suchwinding is attained by engaging the hook in that hole of the series 16farthest from the said pivot.

Near the upper end of the traverseshifter 12 is connected a chain 19,carried over a guide-sheave 20 on the carriage supporting frame 9 andhaving attached to its depending end a weight 21, F ig. 1, which acts inconjunction with the weight W to keep the builder connector B and theintervening connections taut when the carriage and the traverse shifter12 move in unison during the main or service winding, and also when theshifter is rocked during preliminary winding. The forward or right handedge of the shifter 12, Fig. 4, is provided below its pivot with aseries of transverse notches or shoulders 22, 23, 24, 25, arranged onebelow the other and successively nearer a vertical line drawn throughthe pivot 13, any one of the notches being adapted to engage atransverse extension 26 formed on a lever 27 fulcrumed on a stud 28projecting frontward from the lower part of the frame 9, and weighted at29, the extension 26 constituting a shiftable or movable fulcrum for thetraverse-shifter 12 during the preliminary winding, as will beexplained, the weighted end 29 tending to lift the extension 26, whichlatter extends under the carriage, as shown in Fig. 3.

From the foregoing description it will be clear that when the fulcrum 26engages any one of the notches 2225 the lever 12 will rock about suchfulcrum when the builderarm I) rises and falls, the carriage 6 at suchtime having a very slight reciprocatory movement, inasmuch as the pivot13 is a short distance above the shiftable fulcrum, but the carriagereciprocation is so slight that it is of no moment in the operation ofthe apparatus. When the builder-arm rises the lever 12 swings to theright, Figs. 1, 2 and 11-, about the beveled edge of the fulcrum 26, andthrough the chain 18 and connected parts the ring-rail is permitted torise, but its stroke or traverse will be very much shorter than thestroke of the builder-arm, as the chain 18 is connected to the lever 12so near its fulcrum, a layer of the yarn being laid on theyarn-receivers or bobbins during the rise of the ring-rail. The latterdescends when the builder-arm is depressed, but owing to the windingmechanism the builder connector B is given off slightly at each descentof the builder-arm, so that the rail R will not descend quite so low ason its preceding down-stroke, and on its next rip-stroke it will rise alittle higher than before, imparting the gain to the traverse. Theslight gain due to the winding mechanism of the builder-motion isdiminished by the same structure that shortens the traverse duringpreliminary winding, previously explained, so that such winding or bunchtends to be built with too abrupt or blunt ends.

111 my present invention I have provided means to increase the gainduring preliminary winding so that the ends of the bunch so laid will begradually tapered, this increase being effeeted by the cooperation ofthe fulcrum 26 with one after another of the notches 2225. It should beobserved that during preliminary winding the main connector 3, at isslack, as the advance of the carriage 6 is prevented by the fulcrum 26,as explained. Before explaining the means for shifting said fulcrum Iwill describe the manner in which the gain is increased. Should thefulcrum remain in engagement with the same notch during preliminarywinding there would be no increase in the gain, but the fulcrum 26 isautomatically shifted from the notch 22 to engage the notch 23, then thenotch 21, and finally the notch 25, so that by each shift there is anincrement of gain, the total gain being the reduced gain due to thewinding mechanism of the builder-motion plus the increment due to theshift of the fulcrum. By each shift the rail descends to a less degreeand on each upstroke rises higher than would be the case if the windingmechanism alone controlled the gain, so that the increased gain impartedduring the preliminary winding imparts to the yarn mass so laid atapered shape at each end, preventing any catching of the yarn of themain winding when the bobbin is in the loom.

Upon the front of the frame 9 is bolted a bracket 30 which supports theouter end of a stud 31 on which is rotatably mounted a ratchet disk 32having a series of teeth 33 on a portion of its periphery, Figs. 1, 2and 5, and on the outer face of the disk is formed an annular ribconstituting a drum 3%, with a radial rib 35, best shown in Fig. 5,opposite the last tooth of the series 33. ()n the inner face of the disk32 is formed or secured a cam 36, the shape of which is substantially asshown in Fig. 5, the gradual rise of the cam being shown at 3T. Said camis located above the end of the lever 27 nearer the fulcrum extension26, see Fig. 3, and an actuating pawl 38 overhangs the ratchet disk 32and is pivoted at 39 on the traverse-shifter 12, while a weightedstop-pawl 10 is pivoted on a stud etl extended forward from the framet), the pawl 40 having a hook-like extension 12 adapted to be engaged attimes by the pawl 38. By reference to Fig. 8 it will be seen that thesaid pawl 38 is of considerable width, so that such engagement with thedetent or stop-pawl 40 may be effected. The weighted depending tail 43of the stop-pawl serves to normally maintain it in engagement with theratchet disk 32, to prevent rotation of the latter by means of a weightetst attached to a chain d5 carried around and secured to the drum 34.The part of the bracket 30 adjacent the drum 34: is made circular, as atT6, and has a circularly arranged series of holes 17, into any one ofwhich may be inserted a stop -18 which projects into the drum in thepath of the rib 35. The angular movement through which the pawl 38 turnsthe ratchet disk 32 determines the amount of yarn to be laid in thepreliminary winding, the farther ahead the setting of the ratchet whenwinding is begun the smaller the bunch, and conversely the larger willbe the bunch the greater the number of teeth 33 to be engaged by thepawl 38.

I have shown the stop 48 as positioned in the third hole from the bottomof the series 47, and on the first swing of the traverseshifter 12 tothe right, Figs. 1 and 2, the pawl 38 will engage the first tooth of theseries 33 and as the shifter swings back the disk 232 will be advancedone step in the direction of arrow 4L9, Fig. 2, and slightly changingthe position of the fulcrum-shifting cam 36, the pawl -10 holding theratchet disk in advanced position. This step-bystep advance continues asthe preliminary winding proceeds, the part 37 of the shifting cam actingupon the adjacent part of the lever 27 to shift the fulcrum 26successively from one to another of the notches 22 25, to provide forthe increased gain during the preliminary winding, the chain 45 beinggradually wound upon drum 34, and the carriage 6 moving ahead slightlyas the fulcrum shifts, until the fulcrum 26 is entirely disengaged fromthe traverseshifter. Thereupon the weight WV acts through the chain 18to pull the carriage ahead far enough to tighten the main connector 3,4, the weight 21 assisting, the traverse-shifter 12 assuming theposition shown in Figs. 2 and 4, with relation to the carriage, and mainwinding is at once begun, the traverse-shifter and carriage moving as aunit, the reciprocation of the carriage to lay the yarn with the longtraverse being controlled directly by the oscillation of the builderarm,as will be manifest. If a smaller bunch is to be wound, 6., one withless yarn, the stop 48 would be set in one of the two holes 47 to theright of the position of the stop illustrated in Fig. 2, the ratchetdisk being moved by hand in the direction of the arrow 49 to move thepositioning rib 35 further to the right, and as there would be acorresponding advance movement of the cam 36 obviously the latter wouldthrow the fulcrum 26 out of operation earlier than if the apparatus beset as in Fig. 2. On the other hand if the stop 48 is set in one of theholes to the left the pawl 38 must operate upon a greater number ofteeth 33 in order to cause the shifting cam 36 to throw the fulcrum 26out, and consequently the preliminary winding or bunch will contain moreyarn. The stop can be set in such position that the cam will throw outof operation the fulcrum 26 before any winding has been made, and insuch case no bunch will be formed, inasmuch as the carriage 6 willreciprocate to lay the yarn with the full or long traverse with thefirst oscillation of the builderarm.

It will be evident that the short traverse is effected through therocking movement of the lever 12 relatively to the carriage, suchmovement of the lever also acting through the pawl 38 and cooperatingparts to control the time the preliminary winding shall con tinue, theshifting fulcrum 26 cooperating with the lever 12 to increase the gainwhen winding the bunch, and when the traverse is to be changed orshifted the control by the builder-motion is shifted, by thetraverse-shifter or lever 12, from itself to the carriage, the circularpart of the cam 36 keeping the fulcrum out of engagement with thetraverse-shifter 12.

lVhen the ratchet disk 32 has been turned until the last tooth of theseries 33 is engaged by the detent pawl 40 further advance of the diskand the drum 34 ceases, but as the carriage advances to the right thepawl 38 finally engages the hooked end 42 and disengages the detent pawlfrom the ratchet teeth, the weight 44 at once acting through chain 45 toreversely rotate the drum and disk back to starting position, so thatthe parts are thereby set automatically. This occurs soon after the mainor service winding begins and the continued advance of the carriage 6will finally cause the pawl 38 to ride up over and past the top of thedetent pawl 42, and when winding back is per formed, after a set ofbobbins has been wound, the carriage is moved to the left to startingposition, the pawl 38 sliding up over the head of the pawl 40 and thevarious parts are in position to start the winding of a new set ofbobbins.

It is not necessary that each advance of the angularly movableinstrumentality for controlling the quantity of yarn in the preliminarywinding shall be coincident with a shift of the fulcrum for thetraverse-shifter, for the stroke of the actuating pawl 38, the size ofthe teeth 33, and the shape of the fulcrum-shifting cam 36, any or all,may vary the relation between the advance and the fulcrum shifting. Forinstance, it might be desirable that the ratchet disk 32 be advancedseveral steps for each shift of the fulcrum 26, or each advance might beaccompanied by a fulcrum shift. In the latter case, if there are onlyfour seats or notches with which the fulcrum cooperates, as in thestructure herein illustrated, it will be manifest that the fulcrum willbe wholly disengaged from the traverse-shifter when four shifts of saidfulcrum have been made coincidently with four advance steps of theratchet disk or controller. As a matter of fact in the structureillustrated a plurality of advance steps of the ratchet disk will bemade for each shift of the fulcrum for the traverse-shifter.

In Fig. 6 the yarn-receiver or bobbin is of usual construction, thebarrel being made cylindrical near the head 50, as at 51, and upon suchcylindrical portion the preliminary winding or bunch of yarn 52 is laid,and thereafter the main or service winding of yarn is laid, indicated bythe dotted lines 53. As described the preliminary winding is laid withthe shorter traverse, but with the augmented gain, to impart to thebunch the taper 54 at its ends, the main winding being laid with thelonger traverse.
